Question

The colour of sodium bicarbonate is _______.

• A. pale pink
• B. white
• C. pale green
• D. yellow

Answer 1

The correct option is B white

Sodium bicarbonate ($NaHC{O}_3$) is white in colour.

Colour of some common salts:

• Sodium chloride (NaCl) - White
• Sodium carbonate ($N{a}_{2}C{O}_3$) - White
• Copper sulfate ($CuS{O}_4.5H_{2}O$) - Blue
• Ferrous sulfate ($FeS{O}_4.7H_{2}O$) - Green

Note: The colour of copper sulfate and ferrous sulfate is due to water of crystallization present in them. Anhydrous form of both the salts is white.
